This safe is conmovable manner and normally held, and assostructed with a compartment l4 separated from 40 ciated with mechanism to cause the sounding of the atmosphere by a wall formed with a plurality the alarm when these rods move in predeter of openings l5. Anacoustic alarm I5 is mounted mined manners.

ence will be had to the following description and A means is provided for operating the alarm 50 accompanying drawings, and to the appended IS in the event that the safe is lifted'from the claims in which the'yarious novel features of ground by unauthorized persons who do not prop- "the invention are more particularly set forth. erly set the alarm prior to lifting. This means In the accompanying drawings forming a macomprises a rod l1 vertically slidable within a terlal part of this disclosureaa compartment [8 formed in the safe and havinga s5 head I! on its bottom end extendable through an opening 28 in one of the legs of the safe and engaging the ground. A spring 2I acts between the head I3 and a portion of the safe for normally urging the rod I1 downwards. A bracket 22 is attached upon the upper end of the rod I1 and carries the contact 23 engageable with a stationary contact24 constituting a switch for operating thealarm as hereinafter described in detail.

Another arrangement is provided for causing the operation of the alarm when certain drawers of the safe are opened as for example, drawers I0 This arrangementcomprises levers25 pivotally mounted intermediately at 26 upon thesafe and" having their tail ends disposed in the pathpf motion of the drawers Ill and their other ends supporting fingers 21 attached upon rods 28 vertically slidably mounted within the compartment I8. As shown on the drawing, there are'two adjacent-vertical rods 28, each provided with one of the: fingers 21 and each ofthe fingers 21 is supported by one of the ends of the levers 25. The arrangement issuch that if one oi. the drawers I8 isopened, one of the rods will move downwards under the force of gravity and if the other drawer II] is opened. then. the other rod moves downwards. One of the rods28 is provided with a bracket29 at its top carrying a contact 30 engageable with a stationary contact 3I arranged in the alarm circuit as hereinafter fully explained. The other rod28 isprovided with a head piece 32 carrying acontact 33 engageable with a stationary contact 34 also in the alarm circuit as herein: after further explained. 1

arrangement is also provided'foroperating I the alarminthe event. that {the external control handles 42 are not set in proper places upon the scales 58... .These external control handles are arranged iriassociation with internal switches 35 and switches 38. Each of the internal switches 38 is pivotally supported intermediatelyat 31 and is -engageable with stationary contacts 38' on moon-jshaped memberslfl. The switches 38 are provided with tails 48 which'extend into the path of motion of .the drawers l0- in many positions.

In other positions of the switches the tails 48 are disposed free from the drawers. The switches .38 must be manually moved. The drawers III maybe manually opened and closed only when the. switches 38 are in such positions that the tails4fl do not obstruct motions oi the drawers. The featured this arrangement lies in the fact that the drawers cannot be opened except if the switches are'set to certain positions.

The switches. 35. are self closing and mounted behind slots. 4I formed in the safe slidably sup.- porting the control handle 42 which have wing inner ends 43 adapted to selectively pry openthe switches .35. The switches 35 connect with leads 45 and in series with the contacts in the moon-shaped member 39. The. contacts 38', the leads 45 and the switches 35 are arranged in parallel with each other. All of the switches 35 and the leads 45of one of the switches 38 are arranged in one vertical rowto be contrclled by one of thecontrol handles 42, and the otherswitches 35 in the leads 45 connected with the other switch 38 are arranged in another vertical rowto be controlled by. the other control handles'42.

A schematic wiring diagram of the device is illustrated in Fig. 8. The loud speaker' I6 is connected inseries with a switch 45, a source of power41 and the switches 35 and 38. A spring 48 normally tends to urge the switch 46 closed.

Thisswitch is held open when the safe door II anyone of the contacts 38" on the other moonshaped members. Since the two switches 38 may contact with two of the contacts 38, it is pointed out that the switches 38 contact with a pair of contacts 38: If the switches 35 are so set by the control handles 42. asjto open the circuits con-. meeting with said certain pair of contacts, then the alarm willnot be sounded in the event that thesaf'e door I I is opened but, if the switches 35 by the control handles 42 are set at the wrong positions then a complete circuit will exist through the alarm I6 which will necessarily sound when the switch 48 is-closed. f d i If anyoneattempts to'carrythe safe awaycwhen it is closed, the alarm circuit will be closed because the contacts 23 andc24 of the mechanism previously described, short circuit the switch 46. When the door of the"s aie is closed the switch control handles .42 may'bemoved up and down opening any'of the switches35 without the alarm sounding. When the door of the safe is closed, if any of the drawers III are opened by tilting the safe or cutting out portions of the safe to reach them,the levers 25 will be caused to move so that the contacts 38and3I or 33 or34 engage each other to close the circuit through the alarm. The con; tacts 23 and 24, 38. and 3I,-and 33 and 34.are arranged in parallel with eachother and shunted across the switch46. When the safe door is open the drawers I 0. may be readily reached but cannot be opened unless the tails 48 of the switches. 38 are moved, for example, to the .dot and dash positions illustrated in Fig. 8. It should be understood that the switches 38 are pivoted at 31 and, therefore, when thetailends 48.are,moved. the

been "illustrated. It should be noticed that the moon-shapedmembers 39 are urged against the contact 38, by reason of springs 50 acting between stationary -elements 5| -and-thefmoon shaped members.- In order that the drawings are not unduly confusedonly two of the leads 45 have been illustrated; but it must be understood that there are more leads 45 as shown inFig. 8. Each otthe leads 45 connect with a contact 385arranged between" the teeth "of the serrated moon-shaped member sothat the switch contact 38 may selectively engage with any one of the contacts 38. 1

An electro-magnet 52 is also arranged in the alarm circuit and has its core connected with cords 58, which connect with the free ends of flat elements 54 hingedly mounted at their other ends 55 upon the inside wallot the compartment I4. These flat elements .54 are provided with top projecting portions 55 which are or the same shape and size and engage-into the openings I5 in the normally closed position or the flat element. Out of line with theprojections 58, there are openings 51 in eachoi the flat elements 54 so that soundwaves may pass through from the'interior compartment I4 to the atmosphere in theievent that the fiat elements 54 are moved from their closed positions.

Cables 53 pass over guiding pulleys 56 and connect with the free ends of the flat elements 54 so that upon retraction of the core of the solenoid, 52, the flat elements 54 are moved to the dot and dash lines, position shown in Fig. 13, in which position communication is established from the interior compartment l4 to the atmosphere. Coaxial springs 58 are mounted upon the pivoted points 55 of the fiat members 54 and act between the flat members and the inner Wall of the safe for normally urging the flat members into their normal positions. Every time the alarm l6 operates the solenoid 52 will be energized and cause the flat members 54 to move to the opened positions so that the sounds from the alarm may reach the exterior. Normally the flat elements 54 are in closed positions. This prevents dust and dirt from entering the compartment l4 through the opening I5. When the alarm functions, for any reason whatsoever, the flat elements are moved to open positions so that the sounds of the alarm may freely pass to the. atmosphere.

While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
